Do I need to buy a VPS to copy the order?

 

If I choose a signal and try to copy the order, do I have to buy a vps ?

 

VPS is recommended.
It is about EA but same advice for the signal subscription:

What happens to EA if I shut computer down!

Kiran Kumar Balloru Madhava, 2017.11.30 04:45

It is advisable to run the EAs in VPS. Cost of VPS starts with around $10 a month.  If you are running the EA in your computer and if you shut down the computer, EA will stop working. No new trades will be placed. Exisiting positions will close if stop loss or profit limits are kept. Hope this info helps. forexveda
